PAINT.

No Drawing.

Patented Apr. 26, 1910.

To all whom it may concern:

Be it known that I, OMER MARCHAND, a

subject of the King of England, and a resident of St. Paul lErmlte, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Paints, of which the following is a full, clear, and exact description.

This invention relates more to paints for metal surfaces.

The primary object of the invention is to provide a paint which will efi'ectually prevent iron, steel or similar metals from rusting, and which is particularly adapted for painting bridges, steel buildings and similar structures.

A further object of the-invention is to particularly provide a' paint which will be cheaper than those ordinarily used, and which will last much longer, and will dry much quicker than the ordinary paint.

With these and other objects in view, the

invention will be hereinafter more particularly described, and will thenbe pointed out in the claims at the end of the description.

While I shall particularly specify certain elements as composing paint and certain methods whereby the paint may be made, it will be understood that I do not limit myself to the particular elements enumerated nor the exact proportions thereof, nor do I limit myself to the method described for making the paint.

To make a white paint I may take certain elements and combine them in the following proportions Muriatic acid 30 "180 ozs.

Sulfate of zinc 1% lbs. Causticpotash 10 ozs. Carbonate of potash 10 ozs.

Zinc in sheets 60 ozs. Aluminum (powdered) 30 ozs.

White lead 1,000 lbs. Turpentine 6 imperial gals. Linseed oil 50 These ingredients may be mixed in any suitable manner, and a good method is to dissolve thesulfate of zinc in a sufiicient quantity of water, and the sheets of zinc separately dissolved in the muriatic acid. The carbonate of potash is dissolved in a proper quantity of Water. The white lead has enough oil mixed-therewith to make a soft paste, and all the ingredients except the white lead are then put into a proper quantity of oil and stirred, and when thispreparation is perfectly mixed, the same is poured into the white leadfand the remainder of the oil is added, and after it is well stirred the powdered aluminum previously mixed in oil or turpentine is added and'the paint is ready for use. If other colors are desired these may be secured by adding the color pigment wanted to this combination, or by substituting the same for a portion or all of the white lead. If desired it will be understood, of course, that in some instances either of the alkalies or zinc salts or the aluminum may be omitted and satisfactory results obtained.

Having thus described my invention, I claim as new and desire to secure by- Letters Patent-:

" 1. A paint composed of a mixture of caustic potash, carbonate of potash, zinc sheets dissolved in muriatic acid, a pigment, and linseed oil.

2, A paint composed of a mixture of zinc dissolved in murlatic acid, sulfate of zinc, caustic potash, carbonate of potash, linseed oil, and a pigment.

3. A paint composed of a mixture of zinc dissolved in an acld, caustic potash, carbonate of potash, linseed oil, and a pigment.

4. A paint composed of a mixture of zinc dissolved in murlatic acid, sulfate of zinc, caustic potash, carbonate of potash, alum num, white lead, turpentine, and linseed 011 I 'in substantially the proportions specified.

5. A paint-com osed of a mixture'of zinc dissolved in an acld, sulfate of zinc, caustic potash, carbonate of potash, aluminum, and linseed oil.

6. A paint composed of a mixture of zinc dissolved in .muriatic acid, aluminum, white lead, turpentine, and linseed oil.

' This specification signed and witnessed this 25th day of June A. D. 1908.
